Chronic kidney disease (CKD) affects a significant proportion of older dogs. Early detection, dietary management, and supportive care extend quality life years for affected animals.
Chronic kidney disease causes a progressive deterioration in wellbeing that is insidious in early stages and increasingly burdensome in advanced disease. Uremic toxins cause nausea, lethargy, altered mentation, and reduced appetite that undermine quality of life as the disease advances. The welfare importance of early detection is that intervention before significant functional loss dramatically slows progression and extends the period of good quality of life. Renal diets, blood pressure management, phosphorus binders, and adequate hydration are the cornerstones of management that can maintain comfortable, engaged life for months to years beyond what would be possible without intervention. End-of-life decision-making should focus on quality of life assessment rather than specific blood values, recognizing that individual dogs tolerate renal disease differently.
